anybody swapped a Lt-1 into something else?

I need help with the stuff like the AIR, PASS/VATS, and mostly the wiring codes/colors. I need to knoe what some of the wires are on the LT-1 harness and my blazers stock harness. What if I unhook the stock AIR system? How do I bypass the PASS/VATS w/o a LT1 Edit or Tunercat?
Ok I got a few on the LT-1 I dont know:
one harness with these wires:red w/black stripe , black , grey
another with orange w/black stripe , black w/white stripe
another with red , blue
another with black w/white stripe, black w/white stripe
another with tan w/white stripe
another with orange , black
another with purple, yellow, black
another with orange,blue,red,green,grey,yellow
and another that i think is for the abs cuz all are small wires brown w/white ,black w/white ,white w/black , pink,brown,brown w/white, green,green w/white,yellow w/black, and a tan

then on the Blazer I got most done
2 10 gauge reds: constant power
black 10 gauge: ground
Pink 10 gauge : ignition
Purple 10 gauge: starter
Grey 12 gauge: fuel pump
Pink (small) windsheil washer pump
Green (small) : water temp
Tan (small): Oil pressure
Brown (small) alt connector

Purple (small) I dont know and need to know

Re: anybody swapped a Lt-1 into something else?

i need to know how I can hook up my stock under hood ecm connector? what will happen when I unplug and disconnect the stock AIR system? how do I bypass the PASS/VATS system with the PASS box or LT1EDIT or Tunercat? Where can I get a LT1EDIT or Tunercat and which is better? Which really important wires do I need to hook up that I listed to get this running soon!? Alot of the bigger wires I know cuz they go to the stock fuse/relay box under the hood and I can trace as good as anybody else! Thanks for your help

your in the right spot for the tech advice on LT1's, but you might want to try the Hybrid and Conversion section also, they could prolly provide a lot of info that we couldnt.

Re: anybody swapped a Lt-1 into something else?

I wouldn't do a swap like that without the factory service manual for the donor and for the recipient.

FWIW, if you use a 1988 GTA upper steering column bowl on many 80's and early 90's columns, you can retain VATS, which is what I'd do, and have seen done on a swap I've helped with.
